Square is a global business technology platform dedicated to empowering sellers of all sizes—from solo entrepreneurs and local pop-ups to international restaurant chains and retail giants—to start, run, and grow their businesses. Founded in 2009 with the invention of the first mobile card reader, Square set out to solve a simple but powerful problem: enabling any business, anywhere, to accept credit card payments. That initial innovation disrupted the financial system's approach to small business and launched Square on a journey far beyond payments.
Today, Square stands as the largest business technology platform serving all kinds of businesses. The Square operating system allows business owners to sell anywhere, work more efficiently, manage inventory, communicate with customers, book appointments, course meals, order online, and access a comprehensive suite of tools designed to unlock endless possibilities for operations of any scale. With more than four million sellers worldwide running on Square, the platform has become an essential partner for commerce in the digital age.
Square's impact is measurable and significant. The company offers over 36 integrated products spanning hardware, software, and financial services. It serves sellers across 8 countries, including the United States, Canada, Japan, Australia, the United Kingdom, France, Ireland, and Spain. In 2023 alone, Square processed 4 billion individual sales transactions and handled $209.6 billion in total payment volume, according to the company's 2023 10-K Annual Report.
The Square ecosystem is built around several core pillars. For payments, Square enables businesses to accept credit cards, debit cards, contactless payments, and digital wallets in person, online, or on the go, with transparent pricing and no hidden fees. Its point-of-sale solutions are tailored to specific industries: Square for Restaurants manages tables, courses, and kitchen orders; Square for Retail handles inventory tracking and multi-location management; Square Appointments streamlines booking and scheduling for service-based businesses; and Square for Services supports contractors, professionals, and mobile workers with invoicing and client management.
Square's hardware lineup is designed for real-world durability and flexibility. Products include the pocket-sized Square Reader for magstripe and contactless payments, the versatile Square Stand that transforms tablets into registers, the all-in-one Square Terminal, the dual-screen Square Register for high-volume locations, and the recently launched Square Handheld—a portable, powerful point-of-sale device that fits in your pocket. Innovations like Tap to Pay on iPhone allow sellers to accept contactless payments with no additional hardware required.
Beyond transactions, Square helps businesses build lasting customer relationships. Tools like Square Marketing enable targeted email and SMS campaigns; Loyalty Programs reward repeat visits automatically; the Customer Directory tracks preferences and purchase history; and Gift Cards drive additional revenue. Square AI and advanced reporting provide actionable insights to help sellers make smarter business decisions.
For team management, Square offers Shifts for scheduling and labor tracking, Payroll for running payroll and filing taxes, Advanced Access for role-based permissions, and Team Communication tools to keep staff connected. These features help businesses of any size operate more efficiently and scale with confidence.
Square Banking extends the platform into financial services, offering business checking and savings accounts with competitive interest rates, Square Loans that provide capital based on sales history with flexible repayments, a Square Credit Card for earning rewards on business purchases, and Bitcoin integration for buying, selling, and holding cryptocurrency directly within the Square ecosystem.
For online selling, Square Online allows businesses to build free, mobile-optimized websites that sync seamlessly with in-store inventory. Online ordering profiles let customers order ahead for pickup or delivery, while the acquisition of Weebly in 2018 strengthened Square's e-commerce capabilities. The integration of Afterpay offers buy-now-pay-later options to help increase average order value and attract more customers.
Developers and partners can extend Square's functionality through the Square Developer Platform, which provides robust APIs, access to the Square App Marketplace, technical documentation, and a global community of commerce innovators. This open ecosystem encourages customization and integration with existing business tools.
Square's evolution reflects its commitment to continuous innovation. Key milestones include the 2013 launch of Square Stand, the 2014 introduction of Square Capital for business funding, the 2015 debut of Square Appointments, the 2017 expansion to the UK alongside the launches of Square Register and Square for Retail,
